MAX98090AEWJ+T Обзор
An audio codec is an integrated signal-processing semiconductor that converts between digital audio data and analog microphone, line, or headphone signals. The MAX98090 belongs to the broader codec hierarchy: audio codec → mixed-signal interface IC → digital and analog signal conversion → portable audio electronics. Its integrated architecture can reduce the number of external components needed for a compact audio subsystem while supporting configurable analog and digital microphone inputs.
The MAX98090 provides a 24-bit audio interface and an I2S-oriented digital audio connection, while its six input pins can be configured for analog or digital microphones, differential or single-ended line inputs, or full-scale differential inputs. The manufacturer identifies the MAX98090 as an ultra-low-power stereo audio codec designed for portable systems. Its WLP package provides a small physical footprint, but the package requires careful PCB layout, exposed-pad thermal management, and assembly controls.
Typical signal paths include digital microphones feeding an I2S-compatible processor, analog microphone or line sources feeding the codec inputs, and headphone or speaker-related audio functions. The flexible input configuration allows one codec family to address portable recording, communication, and multimedia designs. The exact input sensitivity, sample-rate limits, headphone-output capability, and speaker-output current should be confirmed from the manufacturer datasheet for the final application.
The main design consideration is ensuring that microphone and line inputs are correctly configured, bypassed, and referenced. I2S clocking, digital microphone power sequencing, analog grounding, and WLP assembly must be validated together rather than treated as independent blocks. Use the manufacturer datasheet and recommended application information for the complete pin mapping, electrical limits, and PCB land pattern.
This product page synthesizes verified manufacturer descriptions, distributor availability, package information, pricing references, and practical design guidance. Because the supplied data does not include a complete verified pin table or all electrical limits, missing values are explicitly marked rather than inferred. Engineers should consult the Analog Devices MAX98090 datasheet before finalizing a high-volume or safety-critical portable-audio design.

Типичное применение
MAX98090AEWJ+T подходит для 7 применениеs: Portable Digital Voice Recorder, Wireless Wearable Audio, Bluetooth Headset Signal Path, Smartphone or Tablet Audio Subsystem, USB-C Audio Accessory, Industrial Voice Monitor, Digital Microphone Array.
Portable Digital Voice Recorder
The MAX98090AEWJ+T fits portable voice-recording designs that need flexible microphone selection and a compact digital audio interface. Its six configurable inputs can support analog or digital microphone arrangements, while the 24-bit I2S interface transfers audio data to a host processor. The 49-WLP package helps preserve board area in a handheld product, but microphone clocking, input biasing, decoupling, and analog grounding must be designed from the manufacturer reference information.
Рекомендуется
Wireless Wearable Audio
The MAX98090AEWJ+T is suited to wearable audio subsystems where board area and power budget are important. Its ultra-low-power positioning and configurable microphone inputs allow the codec to sit between audio sources and a low-power digital audio processor. The compact WLP package can reduce footprint, although the design must account for acoustic isolation, vibration, battery transients, RF coupling, and the package’s assembly requirements.
Рекомендуется
Bluetooth Headset Signal Path
The MAX98090AEWJ+T can serve as the audio interface in a compact headset or wireless communication device. Its stereo codec architecture accepts configurable microphone and line inputs and connects digitally through I2S, allowing the host controller to handle wireless transport and voice processing. Designers should verify whether the required headset architecture uses analog, digital, or mixed microphone inputs and should budget PCB area for microphone bias, filtering, and decoupling.
Рекомендуется
Smartphone or Tablet Audio Subsystem
The MAX98090AEWJ+T is appropriate for compact multimedia devices that need an integrated codec interface close to a digital audio processor. The 24-bit I2S connection supports digital audio transfer, while configurable analog and digital microphone inputs provide flexibility across voice, recording, and multimedia modes. System integration must account for speaker and headphone routing, ground partitioning, clock sources, EMI from display or power subsystems, and the manufacturer’s recommended WLP layout.
Рекомендуется
USB-C Audio Accessory
The MAX98090AEWJ+T can be used in a small USB-C audio accessory when the accessory converts digital audio into analog microphone, line, or other configured audio signals. Its compact package helps limit connector-adjacent PCB area, and its flexible input scheme can simplify product variants. Designers should verify the USB audio controller’s required sample rate, clock relationship, codec format, analog levels, and whether an external amplifier is needed for the intended output.
Рекомендуется
Industrial Voice Monitor
The MAX98090AEWJ+T may fit a compact industrial voice monitor that captures local audio while keeping the PCB footprint constrained. Configurable microphone inputs allow the designer to select analog or digital microphones according to the acoustic environment, and the I2S interface can feed a processor responsible for storage, alerting, or communications. The design must control acoustic noise, vibration, connector stress, grounding, and thermal conditions; the codec does not by itself determine environmental reliability.
Рекомендуется
Digital Microphone Array
The MAX98090AEWJ+T is compatible with designs that use configurable digital microphone inputs as part of a small audio acquisition system. The codec can accept multiple microphone-related input pins and provide a digital audio path to the host, reducing the need for separate analog routing components. A production design must confirm the number of microphones, supported digital-microphone modes, clock topology, channel mapping, synchronization requirements, and physical acoustic spacing.

Заметки по проектированию
Use the current Analog Devices MAX98090 WLP land pattern and assembly recommendations rather than deriving the footprint from the distributor package dimensions. The 49-WLP is only 3.15 mm by 3.15 mm, so solder-mask definition, paste volume, pad spacing, exposed-pad connection, and board warp can affect yield. Confirm whether the board has adequate exposed-pad copper and whether the assembly process supports the package’s terminal finish.
Separate microphone and line-input routing from switching supplies, display signals, and high-current return paths. Keep analog ground and digital return planning consistent with the codec’s reference architecture, and place decoupling and filtering components according to the manufacturer’s recommended circuit. I2S and microphone clock traces should be routed with controlled length and return paths to reduce data-integrity errors.
Do not assume that another 24-bit I2S audio codec is a drop-in replacement. The MAX98090’s 49-WLP package, input configurability, clock requirements, analog levels, and power architecture must all be checked against the original design. In particular, verify microphone biasing, digital-microphone support, sample-rate limits, channel routing, shutdown behavior, and exposed-pad connections before substituting any alternative MPN.
Validate the complete power path before layout because the supplied distributor data does not specify the MAX98090AEWJ+T supply range or operating current. Check the codec’s minimum and maximum supply voltage, digital-interface voltage levels, microphone bias requirements, startup sequencing, and current budget against the host system. Use the manufacturer datasheet values for capacitor selection and power-limit calculations rather than estimating them from the codec description.
Информация о соответствии
The supplied excerpts confirm an audio codec and WLP package but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The ordering code should not be treated as evidence of those compliance claims.
